95% likelihood climate change is manmade says IPCC

On Friday the Intergovernmental Panel on Climate Change is expected to release the first of four volumes of its fifth comprehensive assessment of scientific knowledge on climate change, known as AR5. The report is expected to state with 95% confidence that most of the observed global warming since 1950 is caused by human emissions of greenhouse gases. It is also expected to provide updated estimates of temperature projections for this century and updates to projections of major climate impacts such as sea level rise and glacier melt.
